The diversity and composition of intestinal microbiota in rainbow trout have been studied using next-generation sequencing (NGS), although few studies have examined the effects of antimicrobials. We evaluated the effect of antibiotics florfenicol and erythromycin and infection with or without on the intestinal microbiota in rainbow trout juveniles (30-40 g) using NGS. Prophylactic oral antibiotic treatments were administered for 10 days before groups of fish were injected intraperitoneally with virulent .

Article Synopsis
  • * Following an injection of Flavobacterium psychrophilum, gene expression and plasma levels of the LS-12 protein were measured, showing no significant changes in plasma concentrations over 15 days.
  • * However, there was a notable decrease in hepatic LS-12 gene expression at 3 and 6 days post-infection for the lower dose group, while indicating an acute-phase response through increased serum amyloid A levels, suggesting LS-12 is not a positive acute-phase protein in these fish.

Flavobacterium psychrophilum is responsible for significant economic losses in rainbow trout aquaculture. Antimicrobial treatment remains the primary means of control; however, there are limited choices available for use. The objectives of the study were therefore to determine the minimum inhibitory concentrations for erythromycin and florfenicol in selected F.

Flavobacterium psychrophilum, the causative agent of bacterial cold-water disease (BCWD) in freshwater-reared salmonids, is also a common commensal organism of healthy fish. The virulence potential of F. psychrophilum isolates obtained from BCWD cases in Ontario between 1994 and 2009 was evaluated.
